Research Abstract

Movement of the center of gravity (COG) of the body during free walking was analyzed three-dimensionally in 25 elderly (G-old) and 25 young adult (G-yng) subjects. Analysis was performed using a three-dimensional method with 2 video cameras (60 fps) and a computer. COG movement was determined using the model described by Braune and Fischer (1899-1904). After subtracting average speed, COG locus projected on each of 3 dimensional planes (sagittal, frontal, horizontal) showed the subject as if walking on a treadmill In the time course of COG during 1 complete cycle (2 steps), G-yng demonstrated well-balanced sideward movements, whereas G-old tended to show unbalanced COG movements with a shifted locus and delayed forward movements. The vertical movements of COG for both groups were synchronized when the time of 1 swing tended to be smaller in G-old than G-yng, whose trend did not change even when body height was considered (G-old<G-yng). The amount of vertical movement was positively correlated to the balance test result, while cadence correlated negatively with forward displacement during 1 walking cycle. From these results it was concluded that COG movement during walking tends to be unstable in elderly individuals as compared with young adults.
